Storyboard Text

  • This area is located at an abandoned malls parking lot. We are going to start ecological succession today, the first stage of it is primary succession and it starts with having rock being turned into soil, and only has abiotic factors at this point. This process takes a very long time and has very slow changes, 200-400 years, and maybe more to make it more fertile soil to grow plants.
  • Eventually, the rock breaks down into soil by weathering and then we begin to see some pioneer species form such as lichen and moss, which introduces biotic factors into the area. This process is what differs primary succession from secondary succession. No matter what happens to the environment after, it will not have to go through this process again. The pioneer species are the first organisms to live in the ecosystem.
  • Pioneer Species
  • After the pioneer species are there, a population of small grasses begin to develop on top of the soil. Currently, at this part, there are only producers and no consumers yet introduced into the area. 
  • After small grasses come up on top of the soil, we see some more fast changes, that adds some bushes to the area as well. This adds more biodiversity to the area and we are forming a community. 
  • Not every ecosystem has a very smooth history, there was a forest fire in this ecosystem from a lightning strike so it had lost all of its organisms and producers. This natural disaster has brought down all of the grasses and only leaves soil back. This means this ecosystem will have to go through secondary succession now and not primary succession.
  • Now, the forest fire has taken away all of the species that were in the area. This took away from its sustainability and now it will have to restart secondary succession but not have to go through primary succession.
